COMPOSITE ELECTRONIC COMPONENT AND MOUNTING STRUCTURE OF THE SAME

To provide a composite electronic component that can suppress unnecessary high frequency components that are superimposed on a transmission line of high frequency signals and a mounting structure of the same.SOLUTION: A composite electronic component 1 is a two-terminal composite electronic component that is surface-mounted on a board 2, and includes a first terminal 6a, a second terminal 6b and a first body part 4 and a second body part 5 which are arranged in parallel between the first terminal 6a and the second terminal 6b. The first body part 4 includes an electrode layer 8 which is electrically connected to at least one of the first terminal 6a and the second terminal 6b, and a first member (dielectric layer DI) which is provided on the mounting surface side with respect to the electrode layer 8 between the first terminal 6a and the second terminal 6b. The second body part 5 includes a second member (magnetic material MG) which is provided between the first terminal 6a and the second terminal 6b. The relative dielectric constant of the second member is lower than that of the first member at the same frequency.SELECTED DRAWING: Figure 3 【課題】高周波信号の伝送線路に重畳する不要な高周波成分を抑制することができる複合電子部品及びその実装構造を実現する。【解決手段】複合電子部品１は、基板２に表面実装される２端子複合電子部品であって、第１端子６ａと、第２端子６ｂと、第１端子６ａと第２端子６ｂとの間に並列配置される第１本体部４及び第２本体部５と、を備える。第１本体部４は、第１端子６ａ及び第２端子６ｂのうちの少なくとも一方に電気的に接続される電極層８と、第１端子６ａと第２端子６ｂとの間の電極層８よりも実装面側に設けられる第１部材（誘電体層ＤＩ）と、を有する。第２本体部５は、第１端子６ａと第２端子６ｂとの間に設けられる第２部材（磁性体ＭＧ）を有する。第２部材は、同一周波数において第１部材よりも比誘電率が低い。【選択図】図３
